What transmission is in a Chevy Trailblazer?
The current Chevrolet Trailblazer uses a GM Hydra-Matic nine-speed automatic transmission. There is no manual gearbox option in US-spec models. The transmission is paired with the Trailblazer’s turbocharged engines and is available with both front-wheel drive and all-wheel drive configurations.
Transmission overview by engine and drivetrain
All active Trailblazer trims with the available turbocharged engines are paired with GM’s Hydra-Matic nine-speed automatic transmission. This setup is used regardless of whether the vehicle is equipped with front-wheel drive or optional all-wheel drive.
- GM Hydra-Matic nine-speed automatic transmission
- No manual transmission option on current US models
- Designed to handle both front-wheel drive and all-wheel drive configurations
- Engine options typically include a 1.3L turbo and a 1.2L turbo, both paired with the same nine-speed automatic
In everyday driving, the nine-speed automatic provides smooth shifts and responsive acceleration, with the 1.3L turbo generally delivering stronger performance for highway merging and overtaking while maintaining efficiency.
Maintenance and practical considerations
Owners should follow GM’s guidance for transmission care and use the recommended fluids and service intervals. The Trailblazer’s transmission is designed for longevity when properly serviced, with routine checks contributing to reliable performance over time.
- Use the recommended Dexron VI automatic transmission fluid, as specified in the owner’s manual.
- Regularly check the transmission fluid level and color, and schedule service at GM-recommended intervals or if you notice any changes in shifting quality.
- Ensure the cooling system is functioning well, especially in hot climates or during frequent heavy-duty use, to prevent overheating.
- Be attentive to signs of transmission trouble—slipping, hard or delayed shifts, or unusual noises—and have a dealer diagnose and address issues promptly.
Overall, the Trailblazer’s nine-speed automatic is the standard drivetrain pairing across current models, providing a balance of efficiency and practicality for urban driving and light off-road use.
Summary
For the Chevy Trailblazer, the transmission of record is GM’s Hydra-Matic nine-speed automatic, paired with either the 1.2L or 1.3L turbo engines and offered with front-wheel drive or all-wheel drive. There is no manual option, and maintenance centers on using the correct transmission fluid and following recommended service intervals to ensure smooth shifting and reliability over time.
Do all Chevy Trailblazers have CVT transmissions?
All RS and Activ models, regardless of drivetrain, include the 1.3-liter engine as standard equipment. All FWD Trailblazers are equipped with continuously variable transmission as standard.
What transmission does a Chevy Trailblazer have?
Both engine options deliver responsive performance and are paired with either a CVT (1.2L) or a 9-speed automatic transmission (1.3L). All-wheel drive is available on all Trailblazer trims, for enhanced traction when navigating tough terrain.
Are Chevy CVT transmissions reliable?
Chevy CVT reliability is mixed, with some drivers reporting issues like random check engine lights and RPMs getting stuck, while others find them smooth and reliable if properly maintained. While Chevy claims its CVTs avoid the "rubber band" effect and offer good fuel efficiency, some sources suggest potential long-term durability issues due to reliance on belts and pulleys. Proper, frequent maintenance, especially transmission fluid changes, is crucial for longevity.

Potential issues
- Performance complaints: Some drivers dislike the "slushy" or disconnected feel of a CVT compared to a traditional automatic, even though Chevy tries to address this with its design.
- Unpredictable behavior: Some recent models have been reported to experience random check engine lights and the RPMs getting stuck at certain speeds, though dealers may claim this is normal.
- Failure points: Problems can arise from worn-out friction surfaces or overheating due to insufficient or incorrect transmission fluid.
- Repair costs: If a CVT fails, it can be expensive to replace because they are often sealed units and repairs can be difficult or impossible.
Factors that improve reliability
- Proper maintenance: Following the recommended maintenance schedule, especially transmission fluid changes, is critical for a CVT's long-term health.
- Driving style: CVTs are not designed for high-performance applications, so avoiding aggressive driving can help extend their life.
- Model-specific variations: Older models or certain specific vehicles may have different reliability records than newer ones, so it's important to check for issues related to the specific year and model.
Do Chevy Trailblazers have transmission problems?
Engine issues, transmission and electrical problems are prevalent in some Trailblazers. Preventive maintenance can help your Trailblazer last up to 200,000 miles or more.
